RE: [xsl] Problem in calling external java function

[Manpreet Singh <singhm@xxxxxxxxxxx>]

Hi,

  Well , i have figured out the problem. 

 The command :

java org.apache.xalan.xslt.Process -in test.xml -xsl test.xsl -out out.xml

 first searches for the java class along with package name ( tester.xyz ) in
the same directory where the xsl and xml are.
If class is not found in the relative path it looks in the classpath
specified in the command 

for example: java -cp "C:" org.apache.xalan.xslt.Process -in test.xml -xsl
test.xsl -out out.xml 

and if still not found it looks in the system classpath (Environment
variable if any).

In my case wrong file was being picked ( i had a class xyz placed in the
directory tester in the same directory as my xml and xsl ), While i was
updating any changes to class xyz in some other location.

Well I know it has been a goof-up, but this can act as a lesson to all of
us. RIGHT?

Thanx for your answers and cooperation.

Regards
Manpreet

Hi,
   The following is the xslt code calling a java class:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";  xmlns:test="C://tester"
exclude-result-prefixes="test">
	<xsl:template match="/">
		<xsl:apply-templates/>
	</xsl:template>
	<xsl:template match="b">
		<xsl:variable name="test1"
select="test:xyz.new('A;B;C',';')"/>
		<abc>
			<xsl:value-of select="test:getNextToken($test1)"/>
		</abc>
	</xsl:template>
</xsl:stylesheet>


The following is the code for the class being called:

import java.util.StringTokenizer;

public class xyz {

  private StringTokenizer tokenizer;

  public CreateMultipleTargetInstance( String specimen, String token ) {
    tokenizer = new StringTokenizer ( specimen, token );
  }

  public String getNextToken() {
    if ( tokenizer.hasMoreTokens() ) {
      return tokenizer.nextToken();
    }
    else {
      return "";
    }
  }
}

When i call this class using the above xslt Through command prompt using the
following command:

java org.apache.xalan.xslt.Process -in test.xml -xsl test.xsl -out out.xml

i get the following error:

file:/C:abc.xsl;
 Line #9; Column #-1; XSLT Error (javax.xml.transform.TransformerException):
java.lang.NoSuchMethodException: For extension function, could not find
constructor
 tester.CreateMultipleTargetInstance([ExpressionContext,] #STRING, #STRING).


The xslt is supposed to return me the first string before ";" i.e A.

...........ANYONE?
